Really, really bad

I don't enjoy re-entering the class and immediately having every eye in the room on my uncovered naked body, but I manage to get to my seat and try to focus on the power point presentation my teacher is going over, grateful to be able to focus on something besides my nudity for even a moment.

"Miss, there's something you need to see" I hear Amy say. "Can I connect my phone to the projector to show you something?"

My face goes white. I can't believe Amy would betray me so thoroughly, but sure enough in a moment my bare form is on the projector in front of everyone. I've never seem myself in this way and I am slightly transfixed as I see myself start to stroke my enormous cock. When I hear myself moan I chance a look around the room. Girls eyes are practically popping out of their skulls. I notice Sarah and Jessica giggling, it looks like Emma is drooling a little and you see that Natasha has snuck a hand into her skirt again. It's not until everyone has seen me blow a sizeable load that my teacher addresses me.

"George, you should be ashamed of yourself" she shouts. "You specifically promised not to touch yourself, and yet we see you putting on this entire lewd display, and in front of one of your impressionable young classmates on top of it. We absolutely cannot let this go unpunished. Come up here in front of the class."

I have **** but to obey and come up front to face a room full of horny girls who have just seen me gratifying myself, completely naked and uncovered.

"George turn around" she instruct me. I obey, once again showing off my bare ass.

"Bend over my desk at the waist," she tell me. "Amy, since you were the victim here, it's only fair to let you participate in the punishment. If you feel comfortable you may give George ten spanks. He surely deserves it."

Amy wastes no time getting up in front of the class and carrying out your punishment. Fortunately compared to Mrs. Jones' ruler Amy's blows aren't particularly powerful, but that doesn't make them any less humiliating.

"Excuse me miss" I hear Jessica, my step sister say. "We all had to watch what George did. Aren't we all victims?"

"I guess you are" my teacher responds thoughtfully. "I suppose anyone who wants to can take a turn giving George 10 spanks. Maybe then he will learn his lesson."

Every one of the 22 girls in the class stand up and form a line behind my bare ass, with Jessica out in front. Jessica is clearly stronger than Amy and trying harder. I struggle to keep from grunting in pain. The girls deploy a variety of different spanking styles. Most are like Amy giving straightforward blows without too much ****, though those do add up over time to be more and more painful. A few, including Natasha don't spank so much as reach out to grab and caress my exposed ass. While this is a welcome reprieve from the flogging, it comes with the unfortunate side effect of returning my erection. Emma seems almost afraid to touch me, barely tapping my with her spanks. Finally Sarah is last in line and she takes much the same tack as Jessica, putting her full **** into each blow. With my ass already red and sore I am shouting by the second blow, and doing all I can to hold back tears by the tenth. I am ordered to stand back up and face the class.

"I'm not sure if that did any good" my teacher announces. "I can see you are still enjoying showing off for the girls. We are going to have to go to more extremes to keep you from putting on any more obscene displays. Natasha you are a girl scout, correct?"

"Yes!" Natasha answers eagerly.

"You should be able to make sure he can't reach to touch himself" she says tossing Natasha some rope from her desk.

Natasha gets right to work, taking the opportunity to push her body up against mine and sneaking a few more gropes of my bare ass in the process. When she is done my arms are tied very firmly behind my back in such a way that I can't cover my cock or my ass in any way. My teacher inspects her work and approves of it just before the bell rings.

"I'll let the other teachers know about your punishment, and I'll be sending a letter home to your parents" she tells me before dismissing the class.
